   MicroRay (DBW 1.2) is now available on geomag.gly.fsu.edu (128.186.10.2)
   under the directory /pub/pics/DBW.microray.src .  It is a small, well-
   commented version of DBW with some features missing and some added.
   Among the missing features are fractals, wood/marble textures, snowfall,
   and mottling.  Some added features are:  a nice dithering algorithm to
   remove Mach banding, variable sky color (different horizon/zenith), 
   and the use of an octree to reduce overall calculation time.  It's
   main purpose is to be a learning tool, which is why it's small and
   well-commented.  Anyone interested in learning the basics of ray-tracing
   would do well to get this program.
